Grinding Machines - an overview ScienceDirect Topics
Grinding machines, like broaching machines, operate over a range of speeds depending on the type of machine being used.These range from approximately 1250 to 2000m min −1, although in high-speed grinding speeds of up to 5400m/min are achievable (Schey, 1987).The two most common grinding applications are cylindrical grinding and surface grinding.

How to Use a Grinding Machine Safely?
Feb 10, 2013 Verify grinding wheels for cracks before mounting. Never operate grinding wheels at speeds exceeding the recommended limit. Never adjust work mounting devices or workpiece while operating. Never exceed recommended depth of cut for grinding wheel or machine. The workpiece must be removed from the grinding wheel before turning off.

GRINDING FEEDS AND SPEEDS
The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.

Grinding Wheel Safety: Respect The ... - Modern Machine Shop
Mar 15, 2003 In short, never over-speed a grinding wheel. The speed of the grinder must be compared to the speed marked on the wheel or package to make sure the machine’s speed is at or below the maximum operating speed of the wheel. Surpassing this rating risks not just wheel breakage but also the safety of shop personnel.

Machine Stiffness - an overview ScienceDirect Topics
The grinding performance of a grinding machine can be greatly improved by increased machine stiffness.The effect of stiffness in a real grinding situation can be shown by the stiffness factor K described in Chapter 2, where K is the ratio of real depth of cut to set depth of cut. A low stiffness factor reflects high grinding forces and low machine stiffness.
